Convincing her

"Really?" she asked.
"Of course, she's very talented," I persisted.
"It must have been fake music, you know music anyone can make. Just banging on pots and whistling isn't called music. Music must have meaning. Kind of like a story. You know how a story has to have a beginning, middle, and end? Well music must have rhythm, technique, and the quality of it must be so that people actually want to listen to it."
"Wait till you see her music. I'm sure she is as talented as Mozart himself!!" I told her.
"Nope, nope, nope. Mozart was a genius. He was simply fantastic. If he were alive to this day, he would be treasured. Treasured I say."
The lady was now frowning at me as how do I dare relate my sister to Mozart.
"You must see! She knows what quarter beats, and quarter notes, and eighth notes, and sixteenth notes are."
The lady was looking at me through the specks of her glasses, I mean if she had glasses.
She seemed shocked that I knew what they were so she followed me take her to my sister.
